EPA Study Guide 2026

For post-renovation cleaning in lead-safe work, a HEPA-filtered vacuum is mandatory. Unlike regular household vacuums, HEPA vacuums are designed to capture 99.97% of particles 0.3 microns in diameter, including microscopic lead dust, preventing it from being recirculated into the air. This is crucial for effective lead hazard reduction.

The primary goal of hazard control measures is to protect workers and others from harm by either eliminating the hazard entirely or reducing the risk to an acceptable level. These measures are implemented based on the hierarchy of controls, aiming to prevent incidents and ensure a safe working environment. Effective controls are essential for compliance and worker well-being.

Hand and face washing removes lead contamination that could be ingested, as ingestion is a significant route of lead exposure.

Interior trim, windows, and doors are prime locations for lead-based paint because contractors historically used durable oil-based lead paint on high-wear surfaces.

Contaminated disposable PPE must be sealed in labeled containers and disposed of according to waste characterization results, and managed as hazardous waste if TCLP testing so indicates.

The hierarchy of controls is a structured, prioritized approach to managing risks, ranging from the most effective to the least effective. It typically includes elimination, substitution, engineering controls, administrative controls, and personal protective equipment (PPE). Following this hierarchy ensures that the most robust and sustainable risk reduction methods are considered first.
